STEAM-=GENERATO R.

SPECIFICATION forming part of Letters Patent No. 266,078, dated. October 17, 1882.

Application filed June 7, 1882. (No model.) Patented in England May 2, 1882, No. 2,074; in France June 27, 1882, and in Belgium June 27, 1882, No. 58,319.

To all whom it may concern Be it known that we, WILLIAM BEESLEY and JAMES BEEsLEY, subjects of the Queen of Great Britain and Ireland, both residing at Barrow-in-Furness, in the county of Lancaster, Kingdom of Great Britain and Ireland, have invented a new and Improved Steam- Generator, of which the following is a specification.

Our invention relates to an improved steamgenerator, which we construct with-two tubeplates arranged at right angles to each other, orthereabout,and connected together bycurved or quadrant-shaped tubes, as described below and shown in the accompanying drawings, wherein Figure 1 is a central vertical section, and Fig. 2 a front elevation, (one door of the smokebox being removed,) of a steam-generator construotedin accordancewithourinvention. Fig. 3 is a horizontal section in line A B of Fig. 1; Fig. 4, a horizontal section in line CD, Fig. 1.

a is a vertical cylindrical shell, into which is riveted, near its lower end, the furnace or firebox I). This furnace or fire-box is entered by the door 0, the opening being surrounded by a ring in the usual way. The part of the shell below the fire-bars constitutes the ash-pit,and is cut away in front to permit access of air. The top of the furnace or fire-box is closed by a tube-plate, 0?, into which is inserted one end of a number of curved or quadrant-shaped tubes, e, the other ends of which pass throngh a second tube-plate, f, let into or forming part of the shell a, and enter the smoke-box g. The chimney his mounted on top of the smoke box. V The generator is provided with all necessary fittings, such assafety-valve, man-hole, and mud-doors. The smoke-box gis provided the tubes, smoke-box, and chimney, for the purpose of cleaning the same.

The operation of the generator is as follows: The products of combustion pass from the firebox into and through thecontinuously-curved fire-tubes, where they are, on account of such curvature,continuously retarded in their passage,and consequentlyimpartagreater amount of caloric to the water surrounding the tubes, and from the tubes said products are by the smoke-box and chimney conveyed to the atmosphere Without in any degree increasing the heat of the steam produced, thus rendering the apparatus in that regard more safe than if the products were conveyed, after leaving the tubes, through ajacket surrounding the steamchamber, as has been heretofore done, in which latter construction no facilities are afforded for direct access to the tubes for cleaning purposes.

What we claim is- In a steam-generator, the combination of the fire-box I), having the opening 0, and covered by the horizontal flue or crown-plate d, with the smoke-box g, provided with doors t', located directly above the opening 0, and a series of continuously-curved flues,e,whereby direct and ready access is had to both ends of the fines for cleaning purposes, substantially as shown and described.
